2; Claims.

This invention relates to demountable roller Skate Wheels, and itsObjectis to. providev a Sim.:A ple, sturdy anti-.friction mounting forskate roll,- ers` which is of simple, inexpensive construction andcomprises few. parts.

More particularly, its object is te provide an arrangement for firmlysecuring a roller to. rotating parts of a hearing in such a manner thatan injured roller may be easily and quickly removed and replaced bya newroller.

According tov former. practice., .it has been eS- sumed that skaterollers will last a long time and that when they are worn down all ofthem can be removed and new ones substituted. Such changes areinfrequent, so that, the time involved iny making the change is oflittle consequence. It is a fact, however. that in fancyy skating.hockey playing and racingl one or more of the eight rellers on a pair ofSkates may split or become otherwise injured. and it is important toprovide en arrangement whereby a perfect roller may be substituted foran injured 0.1164 with a minimum of effort and in the shortest no letime.

This application is a continuation in part of my application Seriall No.672,481, led May 27', 1946, now abandoned.

I have invented an arrangement which supplies this need, and in thefollowing specication will be described what I now consider a preferredembodiment of the invention and will point out its novel features inclaims.

Fig. 1 is an end View of a roller and its bearing, which is madeaccording to and embodies my invention;

Fig. 2 is a sectional side elevation of the structure shown in Fig. 1;

Fig. 3 is an end elevation of a lock ring which is used to hold some ofthe parts together;

Fig. 4 is a partial sectional elevation taken on the line 4--4 of Fig.2;

Fig. 5 is an end elevation and Fig. 6 is a sectional edge View of aspring Washer as shown in Fig. 2. The section in Fig. 6 is taken on Itheline 6-6 of Fig. 5.

I0 designates a skate roller. Such rollers are usually made of wood, butmay be made of fiber, plastic or other material, if desired. The rolleris provided with a central cylindrical bore I I and with counterboresI2, I3 of a larger diameter at either end of the central bore, formingtherewith at transverse shoulders.

20 is a metallic hub externally threaded as at 2| at one end and havingan upwardly extending ange 22 at its other end. The sides of the angeare nat and normal to the axis of the hub. The

2. outer surface of the hub between the threadsl 2l and the flange 22 isknurled to provide s el'lliens 23 parallel to the. axis` of the hub. 2 4designates diametrically opposed holes in the outer side of the ange forthe reception of. a Wrench. The hub has a cylindrical bore 25, in Whichis an an; nular transverse groove 26.

Projecting from thetruk, 30. or the skate is integral axle 3l of reduceddiameter.. This. has. a. reduced externally threaded nortQn 32. at. itsouter end. A rigid transverse shoulder 33 is formed between the truck 3uand the axle 3 I.` t!!g 3 4 are ball bearings, which may be of standardconstruction. Each of these has an inner race ring 3-5 and an outer racering 36. The inner .Sur-.-Y faces of the inner race. rings are of a.damter to fit the axle 3l. The outer surfaces of the outer race ringsfit the bore 25 of the hub. 3l iS a. Space ing bushing, the innerdiameter of which corre.-4 sponds to the diameter of the axle, and itsouter diameter is. substantially the same as the outer diameter of theinner race rings 35.

3,8 is at split lock ring between the outer race rings. This hasinwardly turned endsv 39 by means of which it can be compressed. aSshown by dotted lines. at, 36A in Fig. 3.

In assembling these parts a dust washer 4U is placed on the axle 3|adjacent the shoulder 33. Then one of the bearings 34, the spacingbushing 31 and the hub 20 are placed on the axle. The lock ring,compressed to pass into the bore 25 of the axle, is then inserted, andwhen it reaches the annular groove 26 is allowed to expand and becomesseated in the groove. The other bearing 34 is then placed on the axle,and, after the parts are thus assembled, a dust washer 4I placed againstits inner race ring 35. 42 is a lock Washer, which is placed on the dustWasher 4I. The inner periphery of the lock washer, which is showni indetail in Figs. 5 and 6, is subdivided into a plurality of sections 43,44, which are bent alternately to project from opposite sides of itsouter body 45. 46 is a nut on the reduced threaded end 32 of the axle.When the nut is tightened, all of these Darts except the hub and theouter races of the bearings will be locked to the axle.

The roller I0 is then placed on the hub 20. This may be tapped intoplace as the serrations 23 cut into its bore lI. The counterbores I2, I3are of equal depth and of a diameter slightly in excess of the outerdiameter of the flange 22, so that either side of the roller may beplaced first on the hub, and the roller is forced in until it abuts theange 22.

.48 is a lock washer, similar to the lock washer 42, .but of largerdiameter, which is placed in the center bore I3, and a lock ring 41,internally threaded to engage the threads 2l on the axle, is screwedagainst it. Diametrically opposed holes 49 in the outer surface of thelock ring are provided for the reception of a wrench.

This construction provides an arrangement whereby a roller may bereadily applied to a skate and may be as readily and as quickly removed.

Various modifications in construction, mode of operation, method and useof an invention may and do occur -to others, especially afterbenefitting from knowledge of such a disclosure as that hereinpresented, of the principles involved, but the invention itself is notconfined to the present showing.

I claim:

1. A skate roller having a central bore and counterbores in its sidesforming iiat transverse shoulders normal to the axis of the roller. amei tallic hub having an outer cylindrical surface adapted to 't tightlyin the central bore of the roller, an outwardly extending flange at oneend of the hub within one of the counterbores, the inner surface of saidflange being at and normal to the axis of the hub to abut one of theshoulders in the roller, an externally threaded portion near the otherend of the hub, said hub having an inner cylindrical bore having atransverse groove therein intermediate its ends, an axle having a rigidshoulder at one of its ends and an externally threaded extension at itsother end, a nut on said extension, longitudinally spaced antifrictionbearings interposed -between the inner bore of the hub and the axle,said bearings having inner and outer race rings, a spacer between theinner race rings, said inner race rings and the spacer being clampedbetween the shoulder on the axle and the nut on the extension thereof,an internally threaded lock ring on the threaded portion of the hubwithin the other counterbore in the roller, and a resilient ring betweenthe outer race rings seated in the groove in the hub.
